Application mm: 27, 193:, Serial No. 695,454;

' cleansing water is directed against or sprayed over the dishes to be washed and whereby a part of the water is effective to coincidentally bring about a movement, and preferably a rotative travelling movement of said dishes during the 5 spraying thereof. 1 i a other more specific objects will appear from the description hereinafter, and the features of novelty will be pointed out in the claims.

Reference is to be had tothe accompanying v drawings which illustrate an example of the in-' vention'without defining its limits, and in which 1 is a plan view of the dish washing apparatus; Fig. 2 isa sectional view on the lined-2 of Fig; 1, and Fig. 3 is an exterior elevation of said apparatus.

The apparatus comprises essentially a suitable support on which a carrier for the dishes to be washed is movably mountedin operative relation to a combined actuating and spraying means.

whereby said carrier is movably operated and the dishes thereon are coincidentally sprayed or otherwise subjected to the cleansing action of the water. In the illustrated example, the support comprises an upright container having an outlet at its lower end through which the soiled waste water may escape, said container consist- .ing of an outwardly and downwardly sloping bottom member 5 preferably of concave-convex form provided with a peripheral flange 8 whereby the apparatus is supported in an upright position on the bottom] of a conventional sink or any other equivalent supporting surface. In its illustrated form, the support further includes a hollow shell 8 preferably of cylindrical shape and supported at'a distance above the bottom member 5 in axial and preferably conterminous registry therewith by means of a plurality of lugs 9 or the like, as shown in Figs. 2 and 3; with this arrangement, the space between the lower edgeof the shell 8 and the peripheral edge of the bottom member 5 constitutes an annular exit opening Ill through which the soiled waste water escapes, for instance, to the sink. Theupper end of the shell 8 is preferably closed by means of 56 a cover ll suitably fixed in position, said shell having an opening for the introduction and removal of the dishes, which is normally closed by a suitable closure such as the hinged doors i2 illustrated in Figs. 1 and 3. The construction and arrangement is such that with the doors it a in' the closed position illustrated in Fig. 3, the shell 8, or in other words, the container is watertight, excepting at the bottom where the annular opening ID or its equivalent permits the. waste water to flow from the interior thereof. -The apparatus further includes a carrier which is movably mounted within the container or shell d, which carrier, the illustrated example, is composed of a plurality of superimposed shelves it fixed upon a shaft l4 and secured in spaced rela- 5 tion by strengthening rods l5, as shown in Fig. 2. To facilitate the rotation of the aforesaid carrier, the shaft M has its opposite ends iournalled in ball bearings l6 located in bearings i1 mounted respectively upon the bottom member 5' and the 2 cover II. The shelves i3 may be provided with suitable devices for retaining 'the dishes in the most efficient position thereon for cleaning, the illustrated example showing bars l8, dish and m plate racks I9, saucer and dessert racks 2d, cup racks 2i and tumbler and glass spindles 22, as examples of the devices in question. i

In addition to the parts so ,far described, the apparatus includes a means which operates to rotate the aforesaid carrier andto'coincidentally 3U spray or otherwise direct cleansing water into contact with the dishes to be washed. In the illustrated example, this means comprises a rotor 23 mounted upon the shaft I l and provided with a plurality of blades 24 against which water is as.

directed by a jet nozzle 25, which forms the terminus of one end of a pipe 26,- the other end of which is connected with a pipe 21 extending lengthwise of the shell or container 8 in operative relation to the carrier "-44.1 At its lower end, '40 the pipe 21 projects exteriorly of the container or shell 8 and terminates in an'external water connection 28 adapted to accommodate a hose 29 arranged to be connected with the customary water faucet or the aforesaid conventional sink 45 or to receive a corresponding permanent water connection leading to an equivalent source of water supply. The pipe 21 at intervals throughout its length is provided with jet apertures or spray nozzles 30 which preferably are arranged so to develop sprays in different directions inwardly toward the carrier l3--||, as diagrammatically illustrated in Fig. 2. Suitable locking means 3| may be provided for maintaining the previously mentioned doors I! in their closed position. it

In utilizing the apparatus, it maybe placed, for instance, in an upright position upon the bottom I, of a conventional sink and connected by means of the hose 29 with the faucet 'of the aforesaid conventional sink. By adjusting the doors I! to their open position, thedishes to be washed may be placed upon the individual shelves ii, for instance, in the manner indicated in Fig. 2, after which the doors ll'are closed and locked and the water supply turned on. This water supply passes upwardly through the pipe 21 and in part issues from the openings or nozzles 30 in the form of jets or sprays, which contact with the dishes on the platforms I3, and subject the same to a cleansing and washing action; at the same time, a portion of the water passes into the pipe 26 to the jet nozzle 25 whereby it is directed against the blades and thus causes the rotor 21 to be rotatively actuated, as will be apparent. The carrier ll-ll with the dishes thereon is thus rotated within the container or shell 8 coincidentally with the spraying of the dishes on the platforms It, so "that said dishes are subjected to a most thorough and efflcient cleansing and washing. In addition to this, the water from the jet 25, after it has functioned to actuate the rotor 23, drips downwardly therefrom and subjects the dishes on the platforms 13 to a shower of water from above, which augments the cleansing action of the jets or sprays issuing from the openings or nozzles 30.

The water after it has been directed against the dishes on the platforms 1 3 passes downwardly to the bottom member 5 and because of the downwardly and outwardly sloping form thereof is directed toward the exit opening I through which it flows as waste water into the sink and from thence through the customary drain to the sewer. If the apparatus is otherwise supported than upon the bottom of a conventional sink, suitable provision will be made for receiving and disposing of the waste water which issues from' the exit opening ll.

The apparatus is extremely simple in construction and is automatic in its operation, and after it has performed its cleansing functions may be utilized to thoroughly rinse the dishes with clean water and as a drying rack in which the thoroushly cleaned dishes may be permitted to dry.

The completely dried dishes may then be removed from the apparatus by simply opening the doors I! whereby the interior of the container or shell I is rendered readily accessible. The apparatus may be of minimum weight, so as to be capable of being easily handled and transported, and is of such a nature that it is not likely to become disarranged or inoperative. If desired, suitable provision may be made to facilitate the transportatlo'n of the apparatus from one place to another. It will be obvious that the apparatus may be permanently connected with a suitable source of cleansing water, and that it may be constructed in any suitable shape and in any dimensions to provide the capacity desired. Likewise, any suitable material may be utilized in its construction. u

Various changes in the specific forms shown and described may be made within the scope of the claims without departing from the spirit of the invention.

I claim:

1. In a dishwashing apparatus, that improvement which comprises a bottom member sloping downwardly and outwardly from its center toward its periphery, and a hollow upright enclosing shell corresponding in cross-sectional form to the shape of said bottom member and supported on said bottom member in conterminous relation thereto and at a distance therefrom to provide an exit opening at the periphery of said sloping bottom member for the escape of water waste.

2. In a dishwashing apparatus, that improvement which comprises a hollow container having an annular exit opening at its lower end for the escape of waterwaste, and an upwardly arched bottom for said container in conterminous relation thereto sloping downwardly and outwardly' oumo E. 'BAnozzL'
